摘　　要：福建某工业园区污水处理厂二期设计规模为2.0万m^(3)/d,工业园内的废水主要为石化工业废水。经过对工业园废水水质等特点的充分分析,该工程确定了“企业分类收集池+细格栅及曝气沉砂池+调节池(合建事故池)+水解酸化池+初沉池+生物反应池+二沉池+芬顿高级氧化+三沉池+反硝化深床滤池+加氯消毒”的工艺路线。该工程设计出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)中的一级A标准,污水厂部分概算工程费用为27906.73万元。该项目结合先进工艺和精细化设计,探讨了工业园区混合污水处理厂的部分设计要点,为国内类似工业污水厂提供一定思路和案例参考。The treatment scale of phaseⅡof wastewater treatment plant(WWTP)in an industrial park in Fujian province is 20000 m^(3)/d.The wastewater in the industrial park is mainly chemical wastewater.The project fully analyzed the characteristics of industrial park wastewater quality and determined the process route of"classification collection pool+fine grid and aerated sand sink+regulation pool(joint construction of accident pool)+hydrolytic acidification+initial sedimentation tank+biological reaction tank+secondary sedimentation tank+Fenton advanced oxidation+triple sedimentation tank+denitrification deep bed filter+chlorination".The effluent quality shall comply with the first grade A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002)and the project cost of the WWTP is 279.0673 million yuan.The project combines advanced technology and fine design,discusses some key points of mixed sewage treatment plant in industrial park,and provides certain ideas and case reference for similar industrial WWTPs at home.
